Manipulation is a free browser card game for 2–8 players using two decks. Build sets or same-suit runs of three or more, then reshape the shared table by moving cards between melds—so long as every pile remains valid. Play timed or untimed, across devices with a room code, against bots, or control several seats yourself. Four rotating rounds and a golf-style scorecard reward the lowest score. No download or ChatGPT sign-in required.
